BALANCING WHEELS (ADH ESIVE WEIGHT TYPE)
Preparation Before Adjustment
Remove inner and outer balance weights from the r oad wheel using releasing agent, remove double-faced
adhesive tape from the road wheel.
CAUTION:
• Be careful not scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
CAUTION:
• Use canter hole cone-type clampi ng machines due to clad wheels.
• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and
skip Step 2. below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2.
to calculate the correct size adhesive weight.
1. Set road wheel on balancer machine using the cent er hole as a guide. Start the balancer machine.
2. For tire balance machines that only have a clip-on (ri m flange) weight mode setting, follow this step to cal-
culate the correct size adhesive weight to use. When inner and outer imbalance values are shown on the
balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that
should be used. Select the outer balance weight with a value closest to the calculated value above and
install in to the designated outer position of, or at the designated angle in relation to the road wheel.
a. Indicated imbalance value × 5/3 (1.67) = balance weight to be
installed
Calculation example:
23 g (0.81 oz.) × 5/3 (1.67) = 38.33 g (1.35 oz.) ⇒ 40 g (1.41
oz.) balance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 ⇒ 35 g (1.23 oz.)
37.5 ⇒ 40 g (1.41 oz.)
